socket.io只能在本地使用nginx - socket.io only works locally with nginx

socket.io only works locally with nginx

本文关键字：nginx io socket | 更新日期: 2023-09-27

（PHP使用nginx运行，我使用NODEJS中的socket.io）如果我在本地尝试我的网站（使用2个不同的web浏览器），一切都可以。但是，如果我托管我的网站（托管在我家），我仍然可以用其他计算机访问它，但我的app.js的功能没有执行。。。

这是我从nginx:得到的最后一个错误日志

2016/05/03 14:11:00 [error] 25016#25016: *108 FastCGI sent in stderr: "PHP message: PHP Notice:  Only variables should be passed by reference in /var/www/html/outer_treatment/game/add_message_discussion.php on line 55" while reading response header from upstream, client: 192.168.1.16, server: default, request: "POST /outer_treatment/game/add_message_discussion.php HTTP/1.1", upstream: "fastcgi://unix:/run/php/php7.0-fpm.sock:", host: "192.168.1.13", referrer: "http://192.168.1.13/game.php"

在我处理NodeJS函数的页面中：（位于：/view/game/index.php）

# into the <head>
<script src="/NODEJS/socket.io/socket.io.js"></script>
# into the <body>
var socket = io.connect('127.0.0.1:3000');

我的nodeJs文件app.js：（位于：/nodeJs/app.js）

var app = require('express')(),
server = require('http').createServer(app),
io = require('socket.io').listen(server),
fs = require('fs');
io.sockets.on('connection', function(socket)
{
// here my functions
});
server.listen(3000, "127.0.0.1");

这是我的Nginx默认文件（位于：/etc/Nginx/sites-available）

# the IP(s) on which node server is running.
upstream app_default {
    server 127.0.0.1:3000;
    keepalive 8;
}

    proxy_redirect off;

    proxy_set_header Connection "upgrade";
}

    add_header  Content-Type    application/x-javascript;

}
}

谢谢你，我希望我的问题是足够准确的

我终于解决了我的问题，在index.php文件中我修改了

var socket = io.connect('127.0.0.1:3000');

通过

var socket = io.connect('http://'+window.location.host+':3000');

现在一切正常！：）
